RADIATOR FOR AUTOMOBILES.

Patented May 28, 1907.

Application filed September 17, 1906. Serial No. 334,887-

To all, whom it may concern:

Be it known that I, JOHN A. WILSON, Jr, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Radiators for Automobiles; and Ideclare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which it pertainsto make and use the same, reference being had to the accompanyingdrawings, which form :1 part of this specification.

My invention relates to an improvement in radiators for automobiles,shown in the accompanying drawings, and more particularly set forth inthe following specification and claims.

In the drawings: Figure l is a front elevation of an automobileradiator; Fig. 2 is a cross-sectional view of a detail of the same,showing parts in section; Fig. 3 is a sectional view or line z-z of Fig.2-. Fig. 4 is a sectional view on line i y of Fig. 2.

The obj eot of my invention is an improvement in the construction ofwhat is known as the cellular type of radiators, and consists inconstructing the radiator with seamless tubes j acketed in such a mannerthat the water in circulatin is caused to divide over each tube, therebyagitating the water through out its passage, by which means itstemperature is materially reduced.

Referring to the letters of reference shown in the drawings, A indicatesthe radiator as a whole; B the upper, and B the lower water chambers.

C are seamless copper tubes inclosed within a sheet metal jacket D; Thejacket D is constructed of two parts flanged at their ends to form theend walls of the water chamber, at which point the jacket is soldered orbrazed to the tubes C and also at the junction point d where the sheetsmeet between each of the tubes.

To connect the rows of tubes. to the upper and lower water chambers, thesheet metal jacket after passing through the apertures provided in thewalls of the water chamber is flanged over the walls, as indicated at(P. Solder E, is then run between the tubes and the wall of the watercha nber, as indicated in Fig. 2, thereby securely anchoringthe'radiator-tubes to the walls of the water chambers.

The advantages gained by my improved construction will be readilyunderstood the water in circulating will split over the tubes, asindicated by the arrows in Fig. 2, passing in either direction around.each tube and coming together again between the next pair of tubes willagain divide on reaching the adjacent tube, and so one. By this means,the water is constantly and thoroughly agitated while circulating aroundthe pipes, thereby causing a material reduction of the temperature.

Having thus described my invention, what I claim is 1. In a cellularradiator for automobiles, a

series of tubes, a jacket surrounding each of said tubes forming a waterspace around alining series of tubes, substantially as described.

2. A radiator comprising a series of tubes, and aseries of communicatingjackets surrounding the tubes, the jackets being flanged at their endsand. secured to the correspond ing tubesto form the end walls of theradiator.

3. A radiator com rising spaced water chambers, a series 0 tubes betweenthe chambers, and a series of communicating
